Online financial data APIs and resources

A couple of weeks ago on Twitter, I asked about freely available financial data.

Anyone know where to get stock data in a standard API format (XML, JSON, etc)? Just looking for hi/lo/close data, not real-time.

I may or may not get around to doing the project I wanted the data for, but in the meantime, here’s a list of the suggested resources that people sent in:

- Google Finance API.

- Google Finance’s CSV output (example)

- Google Finance API for gadgets.

- Yahoo Finance’s CSV output (example)

- There’s a stock quote example in this IBM article on using YQL, JSONP, and jQuery.

- The Stock Quote web service from WebserviceX.net.

- Data from Infochimps: AMEX, NASDAQ, NYSE.

- Xignite finance APIs.

Update: Getting stock information with YQL. (via @jonathantrevor)
